So I don't know how to remove the payment for an item in the barter stand,I'm the owner of the stand and I cant remove the payment. Can you help me please?
Unless this has changed fro last world, you can not remove the payment option from a barter stand once it is placed. You may change payment type but not the slot for payment.
Yeah you can, you just have to clear all items in the stand that have been placed there for payment (for every slot). Usually shift-clicking near the spot where it says the payment is present for a given slot will transfer the paid products into your inventory.
